[vtkusers] vtkIdTypeArray: segmentation fault when extracting vtkOriginalPointIds

[Jochen]

Hi Miguel,

hmm, I would iterate through all arrays first, to see which arrays are
available and what's their name:

int n = polydataThresholded->GetPointData()->GetNumberOfArrays();

for(int i = 0; i < n; i++) {
   std::cout << polydataThresholded->GetPointData()->GetArrayName(i) <<
std::endl;
}

Maybe you can also have a look at this example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PointCellIds
VTK/Examples/Cxx/PolyData/PointCellIds 


best regards
Jochen
